I don't mean to be harsh, but I just don't like either of them. I'm no pro myself, but if I were to visit that site for whatever reason, I just wouldn't stay for too long or want to purchase any services from you.
Of the two, the first one is the best. I actually like the header a lot, the car doesn't implicate, IMO, that you only do graphics for cars. I think it shows that you are sleek, cutting edge and different, as that seems to be a high-class, luxury car. Outside of the header, I just don't like the overall flow and arrangement or the fonts of anything else.
Header number two just doesn't do it for me, not really sure why, but it's not legible and I wouldn't be sure what I'm doing there at your site.
Just being honest, if you stick with Header #1 I think that may be a solid foundation though....
